Gospel truth Member. I just did it this way on my 2019 Sierra and after reading the instructions in the owners manual and hitching up to the my single axel utility trailer, it took about 5 minutes following the prompts on the screen. In my case I did not have to re-create the trailer profile. I poked around until I found the option to add TPMS sensors, then chose a two wheel trailer and went immediately into setup. Thanks!
